Star of Wicked to take over from I'd Do Anything winner Jodie Prenger.
Kerry Ellis will take over the role of Nancy in Cameron Mackintosh's Oliver! in the West End.
The award-winning actress who is best known for playing Elphaba in Wicked (pictured above left), will step into role at the end of March 2010.
Oliver! was the focus of BBC1's I'd Do Anything in 2008, the successful prime time show hosted by Graham Norton, with Andrew Lloyd-Webber as head judge. Jodie Prenger won the competition and has played Nancy to sell-out audiences.
Ellis, who has also performed in We Will Rock You in London, will co-star alongside Griff Rhys-Jones who takes over from Omid Djalili as Fagin.
